Step 1 - NEVER ignore an oil warning light.
Now that i have said that. The 2800 rpm is a give-away.
Your oil pressure warning system is based on two sensors that must be in
agreement.
OFten when one goes out of calibration, they fail at certain
frequencies. It happened to me twice.
So the good news is i will asume you only have a sensor failure.
You can check that oil is in fact circulating by pulling the oil cap and
looking.
Then wipe off your face :-)
